The invention discloses a method for extracting and purifying monomeric macamide compounds from maca. The method comprises the steps of smashing plant maca into maca powder, adding an alcohol-acid water solution to carry out multistage countercurrent extraction, and carrying out vacuum concentration after filtering an extracting solution to obtain crude macamide; and separating and purifying by using macroporous adsorption resin, carrying out gradient elution, collecting an eluant, and respectively carrying out vacuum concentration to obtain the monomeric macamide compounds. Because the macamide compound has favorable and stable physical properties under a weak acid condition, a multistage countercurrent extraction method is carried out by using the alcohol-acid water solution, and the alcohol-acid water solution can be used for protecting effective components of macamide during extraction and greatly increasing the extraction ratio of the effective components in maca plants; the macroporous adsorption resin can be repeatedly utilized; the alcohol-acid water solution serving as a solvent is economical and practical; the high-purity monomeric macamide compounds can be conveniently and efficiently obtained, and the purity of each monomeric compound is up to more than 95%; and the method is simple in process, simple and convenient to operate, low in cost and suitable for batch production.

The invention discloses a method for producing a green coffee bean extract. The method comprises the following steps: softening a green coffee bean raw material, and tabletting to obtain flaky green coffee beans; extracting the flaky green coffee beans with mixed solvent of No.6 solvent oil and ethanol; separating the extract with water to obtain an ethanol-water layer and a No.6 solvent oil layer; filtering and concentrating the ethanol-water layer, removing solvent residues from the ethanol-water layer, and drying in vacuum to obtain the green coffee bean extract. According to the method, the green coffee beans are treated by adopting a softening and tabletting method, so that the flaky raw material with broken cells and extraction availability can be obtained, and impurities when the powdered raw material is extracted can be effectively reduced; separation by adding water can be realized by extraction of mixed solvent of No.6 solvent oil and ethanol, and the green coffee bean extract and green coffee bean oil products can be prepared in one step. The method has the characteristics of simple and effective extraction, convenience in separation, high production efficiency, small content of product impurities, industrial production availability, simple process, high content of product effective components and high yield.
